Running MW 1.5.6 over PHP 5.0.4 on Windows, we encounter an "Access Violation" intermittently. We are told that this is fixed in PHP 5.1.2. We are not able to upgrade MW to a newer version very soon. Can anyone say whether we will have problems if we upgrade PHP 5.0.4 to 5.1.2 under our existing MW 1.5.6? TIA. -- Joshua
